What is the use of the car off button?

The function of the car off button is: off is the switch button to turn off the vehicle stability system. When the car is powered on, the vehicle stability system is turned on by default. After long pressing this switch button, the vehicle stability system can be turned off. The vehicle stability system used in cars is a type of active safety device. During the driving process, if the vehicle stability system is shown as turned off on the car dashboard, it is likely that the vehicle stability system has malfunctioned. The working principle of the vehicle stability control system is: when the car is making a quick turn, dodging, or avoiding suddenly appearing cars or animals, and understeering causes the car to slide outward or oversteering causes the car to cross the center line of the road or even spin in place, the computer controls the engine output or any wheel brake to eliminate the phenomenon of understeering or oversteering, improving the dynamic stability of the car.
The OFF button in cars is super practical! For someone like me who has been driving for years, pressing OFF on the air conditioning system stops the entire AC from blowing air and adjusting temperature, especially during spring and autumn when it's neither too cold nor too hot. Opening the windows for ventilation saves power and feels more comfortable. During long drives, turning it off during breaks prevents excessive battery drain and starting difficulties. Safety is also important—for instance, when the AC fan keeps interfering with visibility, OFF can shut it down to ensure focus. The key benefit is prolonging component lifespan; the compressor runs less frequently, reducing wear and saving money on long-term maintenance. Saving a bit of fuel is another small advantage, as the compressor doesn’t consume engine power. Whether cruising in the city or driving on highways, making a habit of turning OFF is more beneficial than not.
